On Thursday, a German court ruled that Amazon’s Dash buttons violate the country’s consumer protection laws, according to Reuters.

Dash buttons are about the size of a thumb drive, and they can be purchased by Prime members for a variety of different products like coffee, tissues, or laundry detergent. By pressing the button, shoppers can purchase a product instantly and have it shipped to their home. According to the German court, these devices do not provide enough information about the product being purchased or its price, which violates German consumer protection laws that state that shoppers have a right to know the price they’re paying when they make a purchase.
